“I thought on a lot of those 3s, especially early in the game, we had a hand in his face and a hand in his shots,” Thunder guard Thabo Sefolosha said. “So we did a decent job, but those shots went in, and that boosted their whole team.”

The Thunder suffered their worst home loss since moving to Oklahoma City.

“We have to get more physical,” Durant said. “I’m not talking about hard fouls, I’m talking about jamming the lane, fighting through screens and not letting guys run free. We just have to be more physical.”

Both teams were coming off Game 7 wins in the first round on Saturday night, but only the Thunder looked weary. Oklahoma City opened by taking a 16-10 lead, but the Clippers responded with a 24-6 run. Paul hit five 3-pointers in the first quarter, matching his career high for 3s in a playoff game in the first 12 minutes. The Clippers shot 67 percent in the first quarter to take a 39-25 lead.

“I’ve never seen him this aggressive,” Clippers coach Doc Rivers said. “He felt like he needed to set the tone.”

Los Angeles extended its lead to 24 points in the second quarter and took a 69-52 halftime lead, with Paul getting 22 points and six assists.

Durant and Westbrook scored 16 points each in the first half, but the Thunder committed 11 turnovers before halftime.

A quick 3-pointer and a pull-up jumper by Paul pushed the Clippers‘ lead to 78-56 in the opening minutes of the third quarter. The Clippers reached 100 points with just over a minute left in the period and led 104-78 heading into the fourth quarter.

The score that matters to the Thunder is 1-0. They were behind 2-1 and 3-2 against Memphis in the first round and rallied to win the series.

“We just understand that we don’t go into Game 2 with a 17-point lead,” Paul said. “You know, you’ve just got to come back and be hungry and not be satisfied with one.”
